To produce the paper, forming the basis of my invention, I reduce tobacco stems or leaf to a very fine powder to which is added a solution of wheat gluten in dilute acetic or phosphoric acid. The mass is then washed with pure water to free it from acid; The resultant combinationis partially dried and cornbinedwith rice jelly or paste and. thoroughly rmxed so as to form a lastic. consistencyadapted to be assed t ough cold lmbefore named mass obacco in fine powrollers to be rolled severa times the thickness that 1t s desired to-make the sheets after which the sheets are rolled between hot calender rolls the heat being sufiicient topartly cook the rice and hardening and comressmg the other ingredients into a compact r rolling a very-small percentage of moor orated after the "acid was rocess preferthe'following pro ortions for the hereder.
